IGBTs are voltage-controlled power transistors, that have higher current densities than equivalent high-voltage power MOSFETs. (International Rectifier now with Infineon)
Each module consists of one IGBT Transistor having a reverse-connected superfast recovery free-wheel diode and an anode-collector connected superfast recovery free-wheel diode. The Powerex Chopper IGBTMOD Modules are designed for use in switching applications.
IGBT module from Hitachi. The new IGBT module makes high energy efficiency and silent operation of inverters possible. It has High thermal fatigue durability. It is a High speed and low loss IGBT module.
